I am a watch collector and this is my Bell and Ross BR 01-94 46mm steel chronograph with black face purchased from Westime in LA. I wore this watch very little as I rotate all of my watches frequently and I tend to be a perfectionist. So it was never worn in any 'aggressive' activities; although, that was its' intention in design. Below are the details from the Bell and Ross site. I am also including the original rubber strap, the unworn fabric strap, the black alligator on it currently and a grey shark skin strap. It comes in its' original box with papers, strap changing tools and the outer sleeve. Mechanical automatic movement. Functions: hours, minutes, seconds. Three-counter chronograph (60s, 30mn and 12h accumulators). Date.  Satin-brushed steel case. 46 mm diameter. Screw-in crown. Black dial. Numerals, index and hands covered in a photo-luminescent coating.  Anti-reflective sapphire glass.  Water-resistance: 100m. Black rubber and heavy-duty synthetic fabric straps. Pin buckle in satin-brushed steel. To create the BR 01 aviation watch, our designers took their inspiration from aeronautical instrumentation, the ultimate reference point for legibility and reliability. Available in a variety of models, the BR 01 Instrument watch is no longer exclusively reserved for pilots. It has become an iconic watch to the great delight of watch collectors. $6,200.00
